Core Solid

<p>Core is timeless, like the Helvetica font or The Beatles. With its minimalist design and neutrality, it can adapt to any layout.&nbsp;The Flat style is easy to integrate into projects that need icons with a more illustrative purpose, working best at larger sizes. All Core Flat icons are designed on a 14px grid with two customizable colors.</p>

**Summary**: Core's illustrative sub-style — solid flat two-tone blue fills on rounded silhouettes, suited to onboarding flows, feature explainers, and educational content at display sizes (32px+). The controlled two-tone blue tonal system is neither warm nor cold, neither schematic nor expressive, producing a diagrammatic quality that communicates "we illustrate without illustrating." The tone is informational and calm: functional illustration rather than brand storytelling. Best for illustrative onboarding, help and documentation feature explainers, and products with a two-tone blue brand palette that need display-size icon weight without the full expressiveness of gradient fills.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Solid flat fills, two-tone |
| Corner treatment | Rounded silhouettes |
| Color | Two-color: dark blue + light blue tonal |

### Emotional Scores

Core Flat is near neutral on warmth — the dark blue and light blue tonal system is controlled and reads as neither warm nor cold. It is near neutral on softness — the flat fills add visual weight while the rounded silhouettes offset it, producing a genuine midpoint. It is somewhat friendly — the two-tone blue is more neutral-professional than its Sharp equivalent, landing just on the warmer side of the midpoint. It is near neutral on playfulness — flat fills in a tonal system read as diagrammatic rather than expressive or severe. On its human↔mechanical character, it is somewhat mechanical — the flat geometric fills read as schematic, though rounded silhouettes reduce this quality slightly.

---

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter or DM Sans — the two-tone blue tonal system is neutral enough that the standard humanist sans pairings work cleanly
- **Alternative**: Outfit — slightly warmer, appropriate if Flat is being used in more illustrative consumer contexts
- **Avoid**: Expressive display or decorative fonts — they compete with the flat fills


<p>The Helvetica of icons. Core is stripped to essential form with generous spacing. It's a timeless workhorse for interface design.</p>
